Fluorosilicones are a family of elastomers that combine fuel and solvent resistance with low-temperature and high-temperature performance. During the 1950s, chemists at Dow Corning created fluorosilicone rubber (FSR, FVMQ) by modifying Silastic®, a dimethyl silicone, for sealing applications in the automotive and aerospace industries. The first fluorosilicones had modest mechanical properties, however, so many engineers began using FKM fluorocarbons instead.
